LoL on the Cars etc. It does take a long time to get a mode just right. I
farted around with the 892 mode I spoke of for about an hour before I got it
perfectly displayed on the screen. I have a small issue in the bottom right
corner but it is only noticable if I walk right up to the TV. I need to
recalibrate the tv at this resolution as it looks like Geometry issue. I
noticed a similar thing with the left side of the screen. If I shifted the
picture too far to the left it would go very dark and be barely legible.
Pulling it back slightly would solve that. I found a link earlier that
listed a mode for my TV, it was 1776x1000 but unfortunately it didn't work
either for whatever reason. :-( I even tried hooking up the Component
converter box that came with my VIdeo Card but apparently it has an issue
with the RED RCA jack, I had never even pulled it out of the bag before but
I guess it is faulty. I get a very Blue screen and unplugging and replugging
the RED has no effect so I am assuming it is pooched. Doh! With it plugged
in I am able to get 1024x768 but that's about it, it's not really ideal for
my 16:9 tv though and not much better than what I have now.
